The branch instruction is no longer conditional when the targets are the
same, so the operand is not necessary and can be removed.

Verifying that the branch instruction reads exec is not actually
necessary because the pattern that we look for already implies that.
This prepares for the next commit which will remove the exec operand
from branches that have the same target. These branches will no
longer read exec, but they should still get the same optimization.

Don't eliminate an instruction that writes registers other than exec and scc.
It is possible that this is eg. an s_and_saveexec and the saved value is
used by a later branch.

While analyzing cache loading performance, hashing the pipeline layout was
surprisingly consuming around 4% of time, sometimes close to the cost of
hashing shader modules.
Turns out we were hashing the pipeline layout on every pipeline creation.
Considering that pipeline layouts are usually deduplicated by the
application, this was amplifying the hashing cost by a big margin.
With Graphics Pipeline Library, we do need to rebuild the pipeline layout
by combining those from each library, but we can memoize the hash of the
descriptor set layout. The cost of re-hashing hashes is negligible since
each descriptor set layout can amount to 1–2KB in size.

It's currently used when LS store output to LDS.
The LS/HS bug fix seems does not affect this case.
But we'd better treat it as other fixed args.

If a compute pipeline is bound after a raytracing pipeline, the
computes shader slot (aka RT prolog) will be overwritten.
To fix this, move the RT prolog outside of the compute shader slot.

Instead of using a SALU instruction to add to the scalar
